BACKGROUND

Nosocomial pneumonias are a common hospital-acquired infection. The riskof such infections is believed to increase dramatically, for example,six to twenty fold, when mechanical ventilation is used on a patient.Ventilator associated pneumonia (VAP) is associated with highattributable mortality, which has been reported to be in the range of 33to 50 percent. Published studies and Meta-Analysis have shown that oralcare of mechanically ventilated patients with a chlorhexidine gluconate(CHG) containing mouth rinse significantly help reduce the incidence ofVAP. Studies have also shown that dental plaque in ventilated patientsbecomes populated with pathogens which can then be aspirated, so removaland treatment of dental plaque is critical in the prevention of VAP.Ventilated patients as well as a significant segment of the populationalso suffer from xerostomia (dry mouth). Without the normal salivaryflow, which not only mechanically washes off bacteria but also containsenzymes, antibodies, and other components important to the immunesystem, xerostomia favors bacterial proliferation. In the case ofmechanically ventilated patients, the xerostomia has been treated byperiodic application of a mouth moisturizer, while the CHG treatmentmentioned above is intended to help reduce or prevent dental plaque,gingivitis, periodontal disease, as well as overgrowth of opportunisticmicroorganisms. In some instances, the mouth moisturizers dry out andbecome white or peelable upon drying. This is an undesirablecharacteristic, not only because health care workers have great concernabout the general appearance of their patients, but it also decreasesthe efficacy of the moisturizer.

Certain oral hygiene products, for treating ventilated patients, arecommercially available. Such products pre-package certain formulationsand applicators, for example, mouth washes or rinses, oral debridingagents, mucosal moisturizers, swabs, and brushes.

However, there continues to be a need for improved methods and productswhich provide greater flexibility and efficacy in treating patientsaccording to their individual indications.

SUMMARY OF THE INVENTION

The present invention provides a method of moisturizing whiledecolonizing mammalian oral tissue as well as an oral care kit andarticles used therein for treating oral tissue. It has now been found,that oral tissue moisturizers presently used in commerical kits with aCHG oral rinse significantly reduce the antibacterial activity of theCHG oral rinse, and that components of these kits chemically inactivatethe CHG. It is extremely important that any treatment regiment formechanically ventilated patients address both the reduction ofmicroorganisms (plaque removal and reduction of opportunistic organismsin the oral cavity) and xerostomia without having the products used foraddressing these problems interact with each other to reduce theeffectiveness of any one of the products when used in combination.

It has now also been found that certain oral tissue moisturizers can beselected, which when used with a CHG oral rinse do not reduce theantibacterial activity of the CHG rinse or reduce the antibacterialactivity of the CHG rinse to a much lesser extent than oral tissuemoisturizers presently used with a CHG oral rinse. We have further foundthat effective moisturizers can be formulated that can form softflexible coatings that do not form self supporting films that may turnopaque and/or peel off. This applies as well to CHG oral gels and otherCHG oral preparations.

The following terms are used herein according to the followingdefinitions.

“Oral tissue” refers to oral mucosal tissue, teeth, whether natural orprosthetic, within the oral cavity, tongue, and lips. For certainembodiments, preferably oral tissue is oral mucosal tissue.

“Mucosal tissue,” “mucous membranes,” and “mucosal membranes” and areused interchangeably and refer to the surfaces of the oral (e.g., mouth)cavity, and other similar tissues. Examples include mucosal membranessuch as buccal and gingival mucosal membranes.

“Decolonizing” and “Decolonization” refer to a reduction in the numberof microorganisms (e.g., bacteria) present in or on tissue that do notnecessarily cause immediate clinical symptoms. Ordinarily fewermicroorganisms are present in “colonized tissue” than in “infectedtissue.” When the tissue is completely decolonized the microorganismshave been “eradicated”.

“Effective amount” means the amount of the one or more antisepticcomponents when in a composition, as a whole, provides antimicrobial(including, for example, antiviral, antibacterial, or antifungal)activity that when applied in an amount, at a frequency, and for aduration, reduces, prevents, or eliminates one or more species ofmicrobes such that an acceptable level of the microbe results.Typically, this is a level low enough not to cause clinical symptoms,and is desirably a non-detectable level. It should be understood that inthe compositions of the present invention, the concentrations or amountsof the components, when considered separately, may not kill to anacceptable level, or may not kill as broad a spectrum of undesiredmicroorganisms, or may not kill as fast; however, when used togethersuch components may provide an enhanced antimicrobial activity (ascompared to the same components used alone under the same conditions).Also, it should be understood that (unless otherwise specified) thelisted concentrations of the components are for “ready to use” or “asused” compositions. The compositions can be in a concentrated form. Thatis, certain embodiments of the compositions can be in the form ofconcentrates that would be diluted by the user with an appropriatevehicle.

“Hydrophilic” or “water-soluble” refers to a material that will dissolvein deionized water (or other aqueous solution as specified) at atemperature of 23° C. in an amount of at least 7% by weight, preferablyat least 10% by weight, more preferably at least 20% by weight, evenmore preferably at least 25% by weight, even more preferably at least30% by weight, and most preferably at least 40% by weight, based on thetotal weight of the hydrophilic material and the water. The component isconsidered dissolved if after thoroughly mixing the compound with waterat 60° C. for at least 4 hours and allowing this to cool to 23-25° C.for 24 hours, and mixing the composition thoroughly it appears uniformclear solution without visible cloudiness, phase separation, orprecipitate in a jar having a path length of 4 cm. Typically when placedin 1×1 cm cell, the samples exhibit greater than 70% transmissionmeasured in a suitable spectrophotometer at a wavelength of 655 nm.

“Hydrophobic” or “water-insoluble” refers to a material that will notsignificantly dissolve in deionized water at 23° C. “Not significantly”means that the solubility in water of the material is less than 5% byweight, preferably less than 1% by weight, more preferably less than0.5% by weight, and even more preferably less than 0.1% by weight, basedon the total weight of the hydrophobic material and the water.Solubility can be determined by thoroughly mixing the compound withwater at the appropriate concentration at 23° C. for at least 24 hours(or at elevated temperature if that is necessary to dissolve thecompound), allowing this to sit at 23-25° C. for 24 hours, and observingthe sample. In a glass jar with a 4 cm path length the sample shouldhave evidence of a second phase which can be liquid or solid and may beseparated on the top, bottom, or distributed throughout the sample. Forcrystalline compounds care must be taken to avoid producing asupersaturated solution. The components should be mixed and observed.Cloudiness or presence of a visible precipitate or separate phaseindicates that the solubility limit has been exceeded. Typically whenplaced in 1×1 cm cell the sample has less than 70% transmission measuredin a suitable spectrophotometer at a wavelength of 655 nm.

“Subject” and “patient” includes humans, sheep, horses, cattle, pigs,dogs, cats, rats, mice, or other mammal.

“Enhancer” means a component that enhances the effectiveness of theantiseptic component such that when the composition less the antisepticcomponent and the composition less the enhancer component are usedseparately, they do not provide the same level of antimicrobial activityas the composition as a whole. For example, an enhancer component in theabsence of the antiseptic component may not provide any appreciableantimicrobial activity. The enhancing effect can be with respect to thelevel of kill, the speed of kill, and/or the spectrum of microorganismskilled, and may not be seen for all microorganisms. In fact, an enhancedlevel of kill is most often seen in Gram negative bacteria such asEscherichia coli. An enhancer may be a synergist such that when combinedwith the remainder of the composition, the composition as a wholedisplays an activity that is greater than the sum of the activity of thecomposition less the enhancer component and the composition less theantiseptic component.

The terms “comprises” and variations thereof do not have a limitingmeaning where these terms appear in the description and claims.

As used herein, “a,” “an,” “the,” “at least one,” and “one or more” areused interchangeably. The term “and/or” means one or all of the listedelements (e.g., preventing and/or treating an affliction meanspreventing, treating, or both treating and preventing furtherafflictions).

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

The present invention provides a method of moisturizing whiledecolonizing mammalian oral tissue. The present invention also providesan oral care kit and articles used therein for treating oral tissue, forexample, using the present method of moisturizing while decolonizingoral tissue. The method and kit include a moisturizer or substantivemoisturizer composition for moisturizing oral tissue. The moisturizer orsubstantive moisturizer composition can be used in combination with amulti-valent cationic antiseptic, for example, chlorhexidine salts suchas CHG, without reducing the antibacterial activity of the multi-valentcationic antiseptic, or if reduced, the antibacterial activity of themulti-valent cationic antiseptic is reduced to a much lesser extent thanoral tissue moisturizers presently used with a multi-valent cationicantiseptic oral rinse.

An oral tissue moisturizer that is compatible with CHG and in certainembodiments does not leave behind significant residue when repeatedlyapplied allows a user or practitioner a high degree of flexibility inmeeting the individual oral care needs of the user or patient. Sincexerostomia and patient oral health is influenced by factors such ashydration and medications, patients may have vastly different needs fororal moisturization. For example, the moisturizer or substantivemoisturizer can be applied at the same time as the multi-valent cationicantiseptic, such as by including the multi-valent cationic antiseptic aspart of the moisturizer formulation, thereby reducing the number of oraltissue applications. In another example, the moisturizer or substantivemoisturizer can be applied at any time that there is an indication thatthe oral tissue is becoming too dry and could benefit from applicationof a moisturizer. Thus, the moisturizer or substantive moisturizer canbe applied before, during, at the same time as, or after application ofthe multi-valent cationic antiseptic, while still providing or evenmaximizing the antibacterial benefits of the antiseptic, including theeffect of the antiseptic to kill opportunistic microorganisms. In manyinstances, the multivalent cationic antiseptic and moisturizer may beapplied to the oral cavity 4 hours or less apart, for example, less than120 minutes apart. In some instances they may be applied less than 60minutes, 30 minutes, 15 minutes, or even 5 minutes apart. In someinstances they may be applied simultaneously.

Multi-valent cationic antiseptics, such as CHG, can persist on oraltissue in the oral cavity for a number of hours, for example, for up to5 hours. This persistence helps keep pathogenic bacterial counts low inthe oral cavity and helps in the prevention of plaque and gingivitis,which is vital for the care of mechanically ventilated patients inhospitals. For certain embodiments, preferably this benefit can besustained using the methods and kits described herein.

In the present methods, the multi-valent cationic antiseptic is appliedas a composition comprising a solution of the multi-valent cationicantiseptic. For certain embodiments, the solution is an aqueous solutionor a water/alcohol solution of the antiseptic. In other embodiments themultivalent cationic antiseptic is an emulsion such as a water in oil oroil in water emulsion.

Compositions used in conjunction with the multi-valent cationicantiseptic are prepared or selected to prevent or minimize interactionof the antiseptic with a material which precipitates the antisepticand/or which can bind with or otherwise react with the antiseptic andneutralize its antibacterial activity. For certain embodiments,including any one of the above method or kit embodiments or any otherembodiments thereof described herein, any composition applied to tissueor for application to tissue (e.g., moisturizer compositions, de-bridingcompositions, multi-valent cationic antiseptic compositions, other oralcare antiseptic compositions, or another oral care composition)essentially excludes any component which when combined with themulti-valent cationic antiseptic causes a precipitate to form which canbe visibly observed.

In the embodiments described herein, whether or not a precipitate isformed can be determined using Test Method F as described below. Anessentially excluded component is not present or is present in an amountsuch that when combined in that amount with the multi-valent cationicantiseptic no visually observable precipitate is formed. For certain ofthese embodiments, the essentially excluded component is not present.

As used herein, a precipitate is a separate phase, e.g., a solid, a gel,or a liquid that separates out from the antiseptic solution, wherein theprecipitate includes multi-valent cationic antiseptic. When such aprecipitate forms, the amount of multi-valent cationic antiseptic thatremains soluble, and therefore active, may have been reduced. The degreeto which the amount is reduced can be determined by assaying the amountof multi-valent cationic antiseptic in the solution in which it residesusing standard analytical techniques, such a liquid chromatograpy, lightabsorbance, and/or other known methods. For example, Test Method C2 maybe used as described below. For certain embodiments, preferably greaterthan 40 percent of the original amount of multi-valent cationicantiseptic remains in the solution. For certain of these embodiments,greater than 50, 60, or 70 percent, or even greater than 80, 90, or 95percent of the original amount of multi-valent cationic antisepticremains in the solution. For certain of these embodiments, theessentially excluded component is selected from the group consisting ofpolyanions of polycarboxylates, polysulfonates, polysulfates, andorganic and inorganic polyphosphates; anions of alkylsulfates,arylsulfates, alkylsulfonates, arylsulfonates, alkylcarboxylates,arylcarboxylates, alkylphosphates, arylphosphates; halide salts; andcombinations thereof, wherein the alkyl groups have a chain length ofgreater than 6 carbon atoms and the aryl groups have 6 or more carbonatoms. For certain of these embodiments, the essentially excludedcomponent is not present or present at a concentration less than 0.1percent by weight of the composition, except halide salts which are notpresent or present at a concentration not greater than 0.2 wt-% byweight of the composition. For certain of these embodiments, theessentially excluded component is selected from the group consisting ofsodium saccharin, potassium sorbate, sodium benzoate, potassiumchloride, sodium chloride, phosphoric acid, citric acid, sodiumcarboxymethylcellulose, carbomers, such as Carbomer 954, and glycerylpolymethacrylate. Alternatively or additionally, for certain of theseembodiments, any composition applied to the oral tissue or forapplication to the oral tissue, for example, the moisturizercomposition, is such that a log reduction in the number of viablebacterial cells of at least 2 is provided when 10⁶ cfu of Pseudomonasauerginosa (ATCC 27853) are combined with a mixture of 1.1 g of thecomposition and 1.5 g of a multi-valent cationic antiseptic compositioncontaining 0.12 weight percent of the multi-valent cationic antisepticaccording to Test Method B. For certain embodiments, including the aboveembodiments, a log reduction in the number of viable bacterial cells ofat least 3, preferably at least 4 or 5 is provided.

For certain embodiments, including any one of the above method or kitembodiments or any other embodiments thereof described herein, themoisturizer or substantive moisturizer composition is such that at least35 percent, preferably at least 40 percent, more preferably greater than40 percent. For certain embodiments, preferably greater than 50 percent,more preferably greater than 60 percent, more preferably greater than 70percent, and even more preferably greater than 80 percent of themulti-valent cationic antiseptic remains soluble when the multi-valentcationic antiseptic is combined with the moisturizer or substantivemoisturizer composition in a weight ratio of 1 part moisturizer orsubstantive moisturizer composition to 1 part multi-valent cationicantiseptic composition containing the multi-valent cationic antiseptic.The amount of the multi-valent cationic antiseptic that remains solublecan be determined, for example, by measuring the amount that can berecovered from a mixture of the moisturizer or substantive moisturizercomposition and the multi-valent cationic antiseptic within 4 hours witha mixture of water and methanol according to Test Method C. For certainembodiments, including any one of the above method or kit embodiments orany other embodiments thereof described herein, the moisturizer orsubstantive moisturizer composition is such that at least 35 percent,preferably at least 40 percent, more preferably greater than 40 percentof the multi-valent cationic antiseptic remains soluble and can berecovered from a mixture of the moisturizer or substantive moisturizercomposition and the multi-valent cationic antiseptic within 4 hours witha mixture of water and methanol according to Test Method C. For certainof these embodiments, greater than 50 percent, greater than 60 percent,greater than 70 percent, or greater than 80 percent of the multi-valentcationic antiseptic remains soluble and can be recovered. It isunderstood, however, that the solvent system should be considered andoptimized for each composition to ensure that control samples of knowncationic antiseptic concentration in the same range as the test sampleachieve complete recovery of the cationic antiseptic. For example, waterand acetonitrile may also be used instead of water and methanol, andtrifluoroacetic acid (TFA), formic acid, ammonium acetate, or ammoniumformate may be used with these solvent mixtures. One skilled in the artwill know how to modify the solvent system. For certain embodiments,including any one of the above method or kit embodiments or any otherembodiments thereof described herein, the moisturizer or substantivemoisturizer composition essentially excludes a component selected fromthe group consisting of polyanions such as polycarboxylates,polysulfonates, polysulfates, and polyphosphates; chelators; inorganicbuffers; anions such as alkylsulfates, arylsulfates, alkylsulfonates,arylsulfonates, alkylcarboxylates, arylcarboxylates, alkylphosphates,arylphosphates; and combinations thereof. Alkyl groups referred to hereinclude those having a chain length of greater than four carbon atoms,preferably alkyl groups of 6 or more carbon atoms, preferably greaterthan 6 carbon atoms. Aryl groups referred to here include those having 6or more carbon atoms. Anions including such alkyl and aryl groups, whichdo not include hydroxyl groups or other polar solubilizing groups, mayprecipitate the multi-valent cationic antiseptic from solution.“Polyanion” as used herein is a small molecule oligomer, or polymerhaving, on average, at least two ionic groups (e.g., carboxylate,sulfate, sulfonate, or phosphate group) per molecule. For certainembodiments, halide salts at a concentration greater than 1 wt-%, 0.5wt-%, or 0.2 wt-% by weight of the composition in a combination of themulti-valent cationic antiseptic and the moisturizer or substantivemoisturizer composition are further essentially excluded. For certain ofthese embodiments, the essentially excluded component is selected fromthe group consisting of sodium saccharin, potassium sorbate, sodiumbenzoate, potassium chloride, sodium chloride, phosphoric acid, citricacid, sodium carboxymethylcellulose, carbomers, such as Carbomer 954,and glyceryl polymethacrylate. Essentially excluded components are notpresent or are present in amounts which allow for at least a 2 logreduction determined according to Test Method B. Alternatively, or inaddition, essentially excluded components are not present or are presentin amounts such that at least 35 percent, preferably at least 40percent, more preferably greater than 40 percent, of the multi-valentcationic antiseptic remains soluble and can be recovered from a mixtureof the moisturizer or substantive moisturizer composition and themulti-valent cationic antiseptic within 4 hours with a mixture of waterand methanol according to Test Method C. For certain of theseembodiments, greater than 50 percent, greater than 60 percent, greaterthan 70 percent, or greater than 80 percent of the multi-valent cationicantiseptic remains soluble and can be recovered. For certain of theseembodiments, the essentially excluded components are not present.

For certain embodiments, including any one of the above method or kitembodiments or any other embodiments thereof described herein,preferably when the moisturizer or substantive moisturizer compositionincludes an anionic compound, the anionic compound is such that a logreduction in the number of viable bacterial cells of at least 2 isprovided when 10⁶ cfu of Pseudomonas auerginosa are combined with amixture of 1.1 g of the moisturizer or substantive moisturizercomposition and 1.5 g of a multi-valent cationic antiseptic compositioncontaining 0.12 weight percent of the multi-valent cationic antisepticaccording to Test Method B. Alternatively, or in addition, preferablywhen the moisturizer or substantive moisturizer composition includes ananionic compound, the anionic compound is such that greater than 40percent of the multivalent cationic antiseptic is soluble when themulti-valent cationic antiseptic and the moisturizer or substantivemoisturizer composition are combined. Preferably greater than 50percent, greater than 60 percent, greater than 70 percent, or greaterthan 80 percent of the multi-valent cationic antiseptic remains soluble.Here, if possible, the anionic compound is selected and used in anamount such that these conditions are met. For certain of theseembodiments, the anionic compound is selected from the group consistingof polyanions such as polycarboxylates, polysulfonates, polysulfates,and polyphosphates; chelators; inorganic buffers; anions such asalkylsulfates, arylsulfates, alkylsulfonates, arylsulfonates,alkylcarboxylates, arylcarboxylates, alkylphosphates, arylphosphates;and combinations thereof. Alkyl groups referred to here include thosehaving a chain length of greater than six carbon atoms. However, alkylgroups of four or less carbon atoms may increase the likelihood that theabove amounts of multi-valent cationic antiseptic remains soluble in thepresence of such anions. Aryl groups referred to here include thosehaving 6 or more carbon atoms. Anions including such alkyl and arylgroups, which do not include hydroxyl groups or other polar solubilizinggroups, may precipitate the multi-valent cationic antiseptic fromsolution. “Polyanion” as used herein is a small molecule oligomer, orpolymer having, on average, at least two ionic groups (e.g.,carboxylate, sulfate, sulfonate, or phosphate group) per molecule. Forcertain embodiments, the group from which the anionic compound isselected further includes halide salts at a concentration greater than0.2 wt-% by weight of the composition.

For certain embodiments, any other composition described herein and usedin combination with the multi-valent cationic antiseptic, for example, ade-briding composition, also essentially excludes these materials andcomponents.

For optimal multi-valent cationic antiseptic activity, for example,maximizing antimicrobial effectiveness, the pH of the moisturizer orsubstantive moisturize is preferably in the mildly acidic toapproximately neutral range. For certain embodiments, including any oneof the above embodiments, the moisturizer or substantive moisturizercomposition has a pH of 3 to 8 or 4 to 8. For certain of theseembodiments, the pH is at least 4.5, at least 5, or at least 6. Forcertain of these embodiments, the pH is not greater than 7.5, preferablynot greater than 7. For certain of these embodiments, the pH is 4.5 to7, preferably 6 to 7.

Because of the presence of saliva and/or mucus secretions as well asother medicaments or compositions that may be administered in the oralenvironment, the moisturizer is preferably substantive to resist beingwashed or dislodged from the oral tissue for a period of time. Forcertain embodiments, preferably at least a portion of the appliedsubstantive moisturizer remains at the site of application for at least1 hour, at least 2 hours, or more preferably at least 4 hours.Substantivity may by evaluated using Test Method E described below.Relatively high viscosities are preferred to reduce migration as well asto provide substantivity (resistance to removal by fluids) to ensuremoisturization for long periods of time. In certain embodiments,including any one of the above embodiments, the substantive moisturizercomposition has a viscosity of at least 20 centipoise (cps), preferablyat least 50 cps, preferably at least 100 cps, more preferably at least500 cps. For certain of these embodiments, the substantive moisturizercomposition has a viscosity of at least 1,000 cps, more preferably atleast 10,000 cps. Most preferred compositions have viscosities of atleast 20,000 cps, more preferably in excess of 50,000 cps. For certainembodiments, the viscosity can be at least 100,000 cps or even at least1,000,000. These viscosities can be conveniently measured by theViscosity Test (Test Method A) described herein. Compositions meet theseviscosity values at 22-25° C., and in certain embodiments even afterheating to 32° C., 35° C. or as high as 37° C., so that when in contactwith mammalian tissue the compositions remain substantive. For certainof these embodiments, preferably the substantive moisturizer compositionincludes a hydrophobic component (e.g., as described below) and/or apolyhydroxy compound and can be spread evenly across the tissue.Clearly, it is also important that the composition wet the tissue inorder to easily coat the tissue without dewetting. This can be criticalto achieving substantivity. Wetting can be achieved by adjusting thevehicle components and/or addition of surfactant(s).

In order to further enhance substantivity of the compositions, forcertain embodiments, polycationic polymers are included in themoisturizer composition. These are not only compatible with themultivalent cationic antiseptic and improve retention by increasingviscosity, but they also increase retention or substantivity byionically binding with the oral tissue.

Moreover, for certain embodiments, hydrophobic water insolublecomponents are included to increase retention. For example, high oil inwater emulsions or water in oil emulsions can resist removal frommucosal tissue due to the water insoluble nature of the oil. Suitableoils include any of the hydrophobic emollients and emulsifiers disclosedin U.S. Pat. No. 6,562,360. In particular, use in the oral cavity ofthose emollients and emulsifiers that are approved for use as foodadditives are particularly preferred. For example, C8 to C18 mono-, di-and tri- esters of glycerin and propylene glycol may be used as well asa variety of edible oils such as vegetable oils.

Compositions comprising the multi-valent cationic antiseptic, alone orin combination with the moisturizer or substantive moisturizercomposition, can provide at least a 2 log reduction in the number ofviable bacterial cells of at least one type of bacteria. Bacterialreduction is generally reported as log₁₀ reduction determined by thedifference between the log₁₀ of the initial inoculum count and the log₁₀of the inoculum count after exposure to the multi-valent cationicantiseptic. For certain embodiments, compositions comprising themulti-valent cationic antiseptic included in the methods and kits of thepresent invention provide an average of at least a 2 log reduction in atest bacteria 30 minutes, preferably in 10 minutes, more preferably in2.5 minutes. For certain of these embodiments, compositions comprisingthe multi-valent cationic antiseptic, alone or in combination with themoisturizer or substantive moisturizer composition, provide an averageof at least a 3 log reduction, preferably at least a 4 log reduction inthe test bacteria.

A bacterial assay can be used to determine when a composition comprisinga multi-valent cationic antiseptic alone or in combination with amoisturizer or substantive moisturizer composition provides sufficientantimicrobial activity. One readily performed assay involves exposing aselected known or readily available viable microorganism strain, such asEnterococcus spp., Aspergillus spp., Escherichia spp.(e.g., E. coli),Staphylococcus spp. (e.g., Staphylococcus aureus), Streptococcusspp.(e.g., Streptococcus pneumonia), Pseudomonas spp. (e.g., Pseudomonasaeruginosa), Enterobacter spp., or Salmonella spp., or othermicroorganism such as Haemophilus influenza or Acinetobacter baumannii,to a test composition at a predetermined bacterial burden level in aculture media at an appropriate temperature. This may be convenientlycarried out using the Test Method B described in the Examples Section.Briefly, in Test Method B, approximately 10⁶ cfu's are inoculated into amulti-valent cationic antiseptic composition, or a moisturizercomposition mixed with a multi-valient cationic antiseptic composition,or a moisturizer composition which includes a multi-valent cationicantiseptic. After incubation for a specific time period, the mixture isneutralized and enumerated by dilution plating.

Compositions comprising the multi-valent cationic antiseptic alone or incombination with the moisturizer or substantive moisturizer compositionmay provide residual antimicrobial efficacy by maintaining an averagelog reduction of at least 1 log, more preferably at least 1.5 log, andeven more preferably at least 2 log, for at least 1 hour, morepreferably at least 2 hours, and even more preferably at least 4 hoursafter application to oral tissue.

Multi-valent cationic antiseptics, such as chlorhexidine, kill bothgram-positive and gram-negative microbes. In addition, they are activeagainst lipid enveloped viruses and fungi. At least one mechanism ofaction is believed to be membrane disruption. Examples of relevantmicroorganisms against which the antiseptics are active, although notnecessarily those normally encountered in the oral cavity, includeStaphylococcus spp., Streptococcus spp., Pseudomonas spp., Enterococcusspp., and Esherichia spp., Aspergillus spp., Fusarium spp.,Acinetobacter spp., and Candida spp. Particularly virulent organismsinclude Staphylococcus aureus (including resistant strains such asMethicillin Resistant Staphylococcus Aureus (MRSA), Staphylococcusepidermidis, Streptococcus mutans, Streptococcus pneumoniae,Enterococcus faecalis, Vancomycin Resistant Enterococcus (VRE),Pseudomonas auerginosa, Escherichia coli, Aspergillus niger, Aspergillusfumigatus, Aspergillus clavatus, Fusarium solani, Fusarium oxysporum,Fusarium chlamydosporum, Candida albicans, Candida glabrata, and Candidakrusei. For certain embodiments, those microorganisms relevant to theoral cavity and oral tissue, for example, of a mechanically ventilatedsubject, include Staphylococcus aureus, Streptococcus pneumonia,Pseudomonas aeruginosa, Haemophilus influenza and Acinetobacterbaumannii, and Enterobacter spp.

For certain embodiments, including any one of the above embodiments, themulti-valent cationic antiseptic is selected from the group consistingof biguanides, bisbiguanides, polybiguanides, polymeric quaternaryammonium compounds, and combinations thereof. Biguanides include thefollowing 2-carbamimidoylguanidine structure of formula (I):

Examples of polybiguanidesinclude but are not limited to PHMB (poly(hexamethylenebiguanide)) andsalts thereof. In one preferred form, PHMB is commercially available asCosmocil CQ from Arch Chemicals Inc., Smyrna Ga.

Polymeric quaternary ammonium compounds include polymers havingquaternary amine groups with at least one alkyl or aralkyl chain of atleast 6 carbon atoms and preferably as least 8 carbon atoms. Thepolymers may be linear, branched, hyperbranched or dendrimers. Examplesof antimicrobial polymeric quaternary amine polymers include but are notlimited to quaternary ammonium functionalized dendrimers such as thosedescribed in U.S. Pat. No. 6,440,405; polymers which are thepolymerization product of quaternary ammonium functional (meth)acrylatemonomers such as those described in U.S. Pat. No. 5,408,022; polyethers,polycarbonates, and polyurethanes prepared from quaternary ammoniumfunctional diols such as those described in U.S. Pat. No. 5,084,096; andthe like

Any soluble salt of the multi-valent cationic antiseptic, including theabove described salts, may be used. For example, where hydrochloridesalts are soluble, such salts are suitable.

“Soluble” as used herein with respect to the multi-valent cationicantiseptic and/or salts thereof refers to solubility in a composition,for example, an aqueous fluid, above the minimum inhibitoryconcentration (MIC) of the treatment microorganism. If the solubilitylimit is less than the MIC, treatment may be ineffective. Preferably thesolubility exceeds the minimum bacteriacidal concentration (MBC).

For certain embodiments, including any one of the above embodiments,preferably the multi-valent cationic antiseptic is a bisbiguanide or apolybiquanide. For certain of these embodiments, the multi-valentcationic antiseptic is chlorhexidine or PHMB. For certain of theseembodiments, the multi-valent cationic antiseptic is PHMB.Alternatively, for certain of these embodiments, the milti-valentcationic antiseptic is chlorhexidine. The multi-valent cationicantiseptic may be present as the free base, but is preferably present asa soluble salt. For example, chlorhexidine may be present as the freebase but is preferably present as a disalt of acetate, gluconate,lactate, methosulfate (CH₃OSO₃ ⁻), or combinations thereof. These saltsall have solubility limits in water in excess of 1 g/100 ml. Forexample, the solubility limit of the digluconate salt is 20 g/100 ml andthat of the diacetate is 1.9 g/100 ml. For certain of these embodiments,preferably the multi-valent cationic antiseptic is chlorhexidinedigluconate (CHG). In one alternative, preferably the multi-valentcationic antiseptic is the hydrochloride of PHMB.

The multi-valent cationic antiseptics are dissolved in an aqueouscarrier, for example water or water and an alcohol, a non-aqueouscarrier, or a combination thereof and protected from light. Protectionfrom light and use of a non-aqueous carrier may help reduce thedegradation of susceptible antispetic compounds over time. When used incompositions comprising less than about 20% by weight water, theseantiseptics are preferably formulated with a hydrophilic carrier thatsolublizes the antiseptic. Examples of suitable solvents for manymultivalent cationic antseptics, including chlorhexidine gluconate,include glycols (compounds having at least two hydroxylgroups permolecule) such as PEGs having a molecular weight below 2000 andpreferably less than 1000 and most preferably less than about 800daltons; glycerin and polyglycerols, propylene glycol, dipropyleneglycol, tripropylene glycol, polypropylene glycol, ethyleneoxide/propylene oxide random or block copolymers, trimethylolpropane,pentraerythritol, sorbitol, panetothenol, glucuronolactone, gluconicacid, and the like as well as other polar solvents such as N-methylpyrrolidone, propylene carbonate, butyrolactone and the like.

Care may be taken when formulating chlorhexidine as well as othermulti-valent cationic antiseptic compounds to avoid inactivation bysequestering it in micelles which may be formed by incorporation ofsurfactants and/or emulsifiers (for example, certain nonionicsurfactants). Some examples of formulations that may be used includehydrophilic ointments; aqueous solutions thickened with polymericthickeners that are either surfactant free or contain surfactants thatdo not reduce the activity of the CHG, such as certain poloxamers; andointments comprising a major amount of a hydrophobic component andpreferably further comprising a hydrophilic component.

The multi-valent cationic antiseptics, such as chlorhexidine, are verybasic and capable of forming multiple ionic bonds with anionicmaterials. For this reason, the multi-valent cationic antisepticcompositions, as well as the moisturizer or substantive moisturizercompositions and other compositions used in combination with theantiseptic compositions are preferably free of anionic compounds thatcan result in precipitation of the antiseptic. Also, thickener systems,if present, are preferably based on non-ionic and/or cationic polymersor emulsifiers. Anionic surfactants useful, for example, as wettingagents, may also need to be avoided. Certain zwitterionic, very watersoluble, or non-precipitating anionic emulsifiers and surfactants may beuseful. Although halide salts were previously believed to cause CHG toprecipitate, it has now been found that salts, such as sodium chloridemay be used at levels up to 0.2 percent by weight of the composition.Therefore, if a system includes CHG or other multi-valent cationicantiseptic, and needs to comprise salts for stability or other purposes,the salt should be evaluated for compatibility with the multi-valentcationic antiseptic. For example, the inhibitory levels of certainreagents like salt or anionics can be different from CHG for a polymericguanide such as PHMB and would require testing. However, gluconate saltssuch as triethanolamine gluconate or sodium gluconate, can be used withCHG. Furthermore, if an additional antiseptic is incorporated into thecomposition it is preferably non-ionic or cationic. If it is cationicthe counter ion should be compatible with both antiseptics ensuringsolubility of both. Attention may be paid to the pKa, pH, acidequivalents, and solubility of polymer in question when potentiallyinhibitory compounds are used in the formulation. However, thesecriteria may be insufficient to determine if sufficient kill can beobtained when a cationic antiseptic is used with a moisturizer orsubstantive moisturizer.

For certain embodiments, including any one of the above embodiments, themulti-valent cationic antiseptic is included in a composition at asufficient concentration such that when applied to mammalian tissue foran adequate time, for an adequate frequency, and in an adequate dose theantiseptic can provide at least a 2 log reduction, decolonize, oreradicate at least one microorganism from the oral tissue. For certainof these embodiments, the concentration is at least 0.05 weight percent(wt-%). For example, for certain embodiments, the moisturizer orsubstantive moisturizer composition contains 0.05 wt-% of a multi-valentcationic antiseptic as a preservative. For certain of these embodiments,the concentration is at least 0.1 wt-%. For certain of theseembodiments, the multi-valent cationic antiseptic is included in acomposition at a concentration of no greater than 2 wt-%, no greaterthan 1 wt-%, no greater than 0.5 wt-%, no greater than 0.4 wt-%, or nogreater than 0.20 wt-%. For certain of these embodiments, themulti-valent cationic antiseptic is included in a composition comprisinga solution of the multi-valent cationic antiseptic at 0.05 to 0.4 weightpercent. For certain of these embodiments, the multi-valent cationicantiseptic is included in a composition comprising a solution of themulti-valent cationic antiseptic at 0.1 to 0.2 weight percent. Forcertain of these embodiments, the multi-valent cationic antiseptic isincluded in a composition comprising a solution of the multi-valentcationic antiseptic at 0.12 weight percent in water and alcohol. In oneexample, the composition is commercially available as PERIDEX (0.12 wt-%chlorhexidine gluconate, 3M Health Care, St. Paul, Minn.).

The multi-valent cationic antiseptics may be used alone, in combination,or with other antiseptics in order to effectively kill microorganisms onoral tissue. Additional antiseptics for use with the multi-valentcationic antiseptic include peroxides, antimicrobial natural oils, andcompatible combinations thereof as provided in U.S. Patent ApplicationPublication No. 2006/0051384 A1; diphenyl ethers, phenols, halogenatedphenols, bisphenols, resorcinols and its derivatives, anilides, andcombinations thereof, provided in U.S. Patent Application PublicationNo. 2006/0052452 A1. Also, antimicrobial lipid antiseptics mayadditionally be used. Such antimicrobial lipids include(C7-C14)saturated fatty acid esters of a polyhydric alcohol,(C8-C22)unsaturated fatty acid esters of a polyhydric alcohol,(C7-C14)saturated fatty ethers of a polyhydric alcohol,(C8-C22)unsaturated fatty ethers of a polyhydric alcohol, andalkoxylated derivatives thereof, or combinations thereof, wherein thealkoxylated derivative has less than 5 moles of alkoxide per mole ofpolyhydric alcohol; with the proviso that for polyhydric alcohols otherthan sucrose, the esters comprise monoesters and the ethers comprisemonoethers, and for sucrose the esters comprise monoesters, diesters, orcombinations thereof, and the ethers comprise monoethers, diethers, orcombinations thereof. Useful antiseptics of this class are furtherdescribed in U.S. Patent Application Publication No. 2005/0058673. Asused herein the term “fatty” refers to alkyl and alkylene hydrocarbonchains of odd or even number of carbon atoms from C6-C18.

Alternatively, the antimicrobial lipid can be a (C8-C12)fatty alcoholester of a (C2-C8)hydroxycarboxylic acid (also often referred to as a(C2-C8)hydroxycarboxylic acid ester of a (C8-C12)fatty alcohol), a(C8-C22)mono- or poly-unsaturated fatty alcohol ester of a(C2-C8)hydroxycarboxylic acid (also often referred to as a(C2-C8)hydroxycarboxylic acid ester of a (C8-C22)mono- orpoly-unsaturated fatty alcohol), or alkoxylated derivatives thereof. Thealkoxylated derivatives have less than 5 moles of alkoxide per mole ofpolyhydric alcohol or hydroxy acid. The hydroxycarboxylic acid moietycan include aliphatic and/or aromatic groups. For example, fatty alcoholesters of salicylic acid are possible.

As used herein, a “fatty alcohol” is an alkyl or alkylene monofunctionalalcohol having an even or odd number of carbon atoms and a “fatty acid”is an alkyl or alkylene monofunctional carboxylic acid having an even orodd number of carbon atoms.

Cationic antiseptic compositions may have a persistently bitter taste.It has now been found that certain non-ionic sweetening compounds can beused together with the multi-valent cationic antispetic to significantlyreduce this bitter taste without significantly diminishing antisepticactivity. We have found that anionic sweeteners employed in thesecompositions previously, such as sodium saccharin, can precipitatecationic actives such as chlorhexidine gluconate. We believe this wouldbe true for many cationic antiseptics. For certain embodiments,including any one of the method or oral care kit embodiment describedherein, the composition including the multi-valent cationic antisepticfurther comprises a sweetener selected from the group consisting ofsucralose, aspartame, sugars and sugar alcohols including but notlimited to xylose, sucrose, maltose, mannose, glucose, xylitol,sorbitol, mannitol, erythritol, maltitol, lactitol, and a combinationthereof.

For certain embodiments, compositions comprising the multi-valentcationic antiseptic also include at least one additional componentselected from the group consisting of enhancers, surfactants,hydrophilic compounds, hydrophobic compounds, and combinations thereof.

Compositions used in the present method and kit can be applied withswabs, cloth, sponges, foams and non-woven and paper products (e.g.,paper towels and wipes), for example where they are used to deliver asignificant portion of the antiseptic composition to the oral tissue. By“significant portion” it is meant that enough composition is applied andallowed to remain on the tissue when applied in a dose, at a frequency,and in an amount sufficient to reduce or eliminate the microorganisms onor in the tissue.

Compositions used in the present method and kit are physically stable.As defined herein “physically stable” compositions are those that do notsignificantly change due to substantial precipitation, crystallization,phase separation, and the like, from their original condition duringstorage at 25° C. for at least 3 months, and preferably for at least 6months. Particularly preferred compositions are completely physicallystable if a 10-milliliter (10-ml) sample of the composition when placedin a 15-ml conical-shaped graduated plastic centrifuge tube (Corning)and centrifuged at about 2275×g (e.g. 3,000 revolutions per minute (rpm)for 10 minutes using a Labofuge B, model 2650 manufactured by HeraeusSepatech GmbH, Osterode, West Germany) or similar centrifuge at acentrifugal force of 2275×g has no visible phase separation in thebottom or top of the tube. Phase separation of less than 0.5 ml is alsoconsidered stable as long as there is no other sign of physicalseparation in the sample.

Compositions used in the present method and kit exhibit good chemicalstability. This can be a concern with compounds that may hydrolyze orundergo heat and/or light degradation such as chlorhexidine. The mostpreferred compositions retain an average of at least 97% of theantiseptic component after aging for 4 weeks at 40° C. in a sealedcontainer beyond the initial 5-day equilibration period at 25° C. Thepercent retention is understood to mean the weight percent of antisepticcomponent retained. This is determined by comparing the amount remainingin a sample aged (i.e., aged beyond the initial 5-day equilibrationperiod) in a sealed container that does not cause degradation, to theactual measured level in an identically prepared sample (preferably fromthe same batch) and allowed to sit at 25° C. for five days. The level ofantiseptic component is preferably determined using gas chromatographyor high performance liquid chromatography using appropriate standardsand controls.

In the present methods, the multi-valent cationic antiseptic is appliedas a composition comprising a solution of the multi-valent cationicantiseptic. For certain embodiments, the solution is an aqueous solutionor a water/alcohol solution of the antiseptic.

As indicted above, the multi-valent cationic antiseptic is included in acomposition comprising a solution of the multi-valent cationicantiseptic, and for certain embodiments, the solution is an aqueoussolution or a water/alcohol solution of the antiseptic. The compositionmay additionally include various other materials as described herein.Alternative compositions where the multi-valent cationic antiseptic isdissolved in or mixed with a non-aqueous hydrophilic material are alsocontemplated.

The moisturizer or substantive moisturizer composition may be used orprovided in various forms including, for example, hydrophobic ointments,oil in water emulsions, water in oil emulsions, thickened aqueous gels,and hydrophilic gels.

Hydrophobic compositions include a hydrophobic base or vehicle (e.g.,petrolatum, insoluble oils, thickened or gelled water insoluble oils andthe like) and may include a minor amount of a water-soluble phase, whichwould include the multi-valent cationic antiseptic if present.Acceptable salts, surfactants, emulsifiers, humectants and/or othercomponents may also be included. Care must be taken to ensure that thecomposition does not degrade or negatively effect the endotracheal tubeused for ventilation or other medical devices that may be in contact orin proximity to the mucosal tissue. Certain hydrophobic components candegrade plasticized PVC which is commonly used as endotracheal tubematerial. Preferably the compositions do not negatively effect naturalrubber latex or nitrile gloves.

Oil in water emulsion compositions include a discrete phase of ahydrophobic component and a continuous aqueous phase comprising waterand optionally one or more polar hydrophilic carriers, where either orboth phases include the multi-valent cationic antiseptic if present.Acceptable salts, surfactants, emulsifiers, humectants, and/or othercomponents may also be included. These emulsions may comprise acceptablewater-soluble or water swellable polymers as well as one or moreemulsifiers that help to stabilize the emulsion.

Water in oil emulsion compositions include a continuous phase of ahydrophobic component and an aqueous phase comprising water andoptionally one or more polar hydrophilic carriers as well as acceptablesalts or other components, where the multi-valent cationic antiseptic ifpresent is in either or both phases. Acceptable salts, surfactants,emulsifiers, humectants and/or other components may also be included.These emulsions may comprise oil soluble or oil swellable polymers andone or more emulsifiers, as well as inorganic salts such as magnesiumsulfate, that help to stabilize the emulsion.

Thickened aqueous gel compositions include an aqueous phase, which wouldinclude the multi-valent cationic antiseptic if present, that has beenthickened to achieve a sufficiently high viscosity as described above,for example, a viscosity of at least 10 cps and preferably at least 20cps. Viscosities of at least 50 cps, at least 100 cps, at least 250 cps,or at least 500 cps may also be preferred. The viscosity is determinedusing the Viscosity Test described herein. These compositions arethickened by suitable natural, modified natural, or synthetic polymersas described below. The thickened aqueous gels can also be thickenedusing suitable emulsifiers such as alkyl alcohols and polyethoxylatedalkyl chain surfactants that effectively thicken the composition.Examples include the Polawax, Behenyl TMS, Crodaphos CES, Cosmowax, andCrothix systems from Croda Inc.

Hydrophilic gel compositions include a continuous phase comprised of atleast one water soluble hydrophilic component other than water. Theformulations may contain water up to 90% by weight. The higherconcentrations may be suitable in some compositions. Suitablehydrophilic components are described below under the heading“Hydrophilic Component.” For certain embodiments, suitable hydrophiliccomponents include one or more glycols (such as glycerin, propyleneglycol, butylenes glycol, etc.), polyethylene glycols (PEG), random orblock copolymers of ethylene oxide, propylene oxide, and/or butylenesoxide, polyalkoxylated surfactants having one or more hydrophobicmoieties per molecule, silicone copolyols, as well as combinationsthereof. One skilled in the art will recognize that the level ofethoxylation must be sufficient to render the hydrophilic componentwater-soluble or water dispersible at 23° C.

As indicated above, the present methods and kits can provide asignificant advancement in antimicrobial effectiveness as well asflexibility in applying the moisturizer composition as needed by apatient. Because the moisturizer or substantive moisturizer compositionmaintains the antimicrobial effectiveness of the multi-valent cationicantiseptic, the moisturizer can be applied at any time in the presenceof the antiseptic. For certain embodiments, including any one of theabove method embodiments, the moisturizer or substantive moisturizercomposition is applied after applying the cationic antiseptic.Alternatively, for certain of these embodiments, the moisturizer orsubstantive moisturizer composition is applied before applying thecationic antiseptic. For certain of these embodiments, the moisturizeror substantive moisturizer composition and the multi-valent cationicantiseptic are applied within 12 hours of each other. For certain ofthese embodiments, the moisturizer or substantive moisturizercomposition and the multi-valent cationic antiseptic are applied within4 hours of each other. For certain of these embodiments, preferably themoisturizer or substantive moisturizer composition and the multi-valentcationic antiseptic are applied within less than 120, 60, or 30 minutesof each other. For certain of these embodiments, the moisturizer orsubstantive moisturizer composition is applied at the same time asapplying the multi-valent cationic antiseptic. For certain of theseembodiments the moisturizer or substantive moisturizer compositioncontains the multi-valent cationic antiseptic, and the moisturizer andantiseptic are applied simultaneously.

Certain commercially available mouth moisturizing products used to treatventilated patients have been found to include components that havefilm-forming properties and often leave behind a peelable, unabsorbedfilm as the product dries on the tissue upon which it is applied. Thisis particularly problematic for mouth moisturizers used in a hospitalsetting on ventilated patients, where mouth moisturizers are used bothinside of the patient's mouth and on the lips. It has been found that assuch moisturizers dry and are re-applied, a buildup of residue can givethe appearance of dried, peeling lips. This can give an appearance orimpression, for example, to hospital visitors, that patients are notproperly cared for. Furthermore, once the film cracks and peels themoisturization “barrier” can be lost.

It has also now been found that such moisturizers shrink to aconsiderable extent when dried. Shrinkage is believed to contribute tothe undesirable appearance. For certain embodiments, including any oneof the above embodiments of the method and kit, levels and combinationsof multi-valent cationic antiseptic-compatible thickeners, humectants,and excipients are combined such that peel-able film formation by themoisturizer or substantive moisturizer composition is minimized and theproduct is more esthetically pleasing when dried on oral tissue, such asthe lips. For certain of these embodiments, the moisturizer orsubstantive moisturizer composition has a shrinkage of less than 10percent when dried under ambient conditions for 2 hours. For certainembodiments, ambient conditions include 22-25° C. and 30 to 50 percentrelative humidity. For certain embodiments, ambient conditions include25° C. and 30 percent relative humidity. Shrinkage is easily determinedby coating a substrate of known area, allowing the composition to dryand measuring the area of the dried composition, for example, accordingto Test Method D. A dried film of at least 50 microns and preferably notmore than 350 microns in thickness may be used. Shrinkage measurementsshould be done on a surface that allows the composition to debond if itis inclined to do so upon drying. This typically means it should be doneon the lowest surface energy substrate that allows one to put down auniform coating without dewetting.

For certain of these embodiments, the moisturizer or substantivemoisturizer composition when dried on a surface, such as the surface ofa clear plastic petri dish, does not form a self-supporting film, thatis, it cannot be peeled from the surface in a single piece. For certainof these embodiments, the dried moisturizer or substantive moisturizercomposition cannot be peeled from the surface in a piece having a sizegreater than 30 percent of the area of the dried moisturizer orsubstantive moisturizer composition. For certain embodiments,self-supporting means that when the composition is dried on a suitablesurface such as a release liner of suitably low surface energy, a filmso formed can be removed from the release liner in a single piece andthe film is capable of supporting its own weight. Evaluation for suchcharacteristics may be carried out using Test Method D described below.Sufficient coating is typically applied to ensure a dried film of atleast 50 microns and preferably not more than 350 microns in thickness.

The moisturizer or substantive moisturizer composition is applied in anamount sufficient to cover oral tissue that is susceptible to becomingexcessively dry and compromised. For certain embodiments, including anyone of the above method embodiments, the moisturizer or substantivemoisturizer is applied in an amount of 1 to 10 grams per application.More may be applied if any excess is removed.

As indicated above, such oral tissue includes, for example, lips,mucosal tissue, tongue, and teeth. For certain embodiments, includingany one of the above embodiments, the oral tissue is oral mucosaltissue. For certain of these embodiments, the oral mucosal tissue isselected from the group consisting gingiva, buccal mucosa, the floor ofthe mouth, the hard palate, the soft palate, the dorsal tongue, thelateral tongue, the ventral tongue, an oropharyngeal surface, andcombinations thereof.

Subjects who may benefit from the present methods include any who have acondition of dry oral tissue. However, mechanically ventilated patients,such as those in a hospital setting, may receive significantly improvedcare. For certain embodiments, including any one of the above methodembodiments, the subject is a patient in an Intensive Care Unit. Forcertain of these embodiments, the subject is a mechanically ventilatedpatient.

For certain embodiments of the oral care kit, including of any one ofthe above kit embodiments, the oral care kit includes at least one doseof the multi-valent cationic antiseptic composition. One dose is anamount sufficient for application to cover at least a portion of theoral tissue of a subject, preferably all of the oral mucosal tissue of asubject.

For certain of these embodiments, the kit includes at least30 mL of the multi-valent cationic antiseptic composition. For certainof these embodiments, the kit includes at least two 15 mL unit dosecontainers of the multi-valent cationic antiseptic composition. Althoughthe amounts are expressed in mL units, these amounts are understood toinclude their mass equivalents. For example, 1 mL of the multi-valentantiseptic composition is equivalent to an amount of 0.9 to 1.1 grams,depending upon the particular formulation density. In the case of thecomposition being in the form of a foam, the amount in grams may be lessthan this.

For certain embodiments, the oral care kit includes the moisturizer orsubstantive moisturizing composition supplied in an amount sufficient tocover at least a portion of the oral tissue of a subject, preferably allof the oral mucosal tissue of a subject, more preferably also includingthe lips. For certain of these embodiments, the moisturizer orsubstantive moisturizing composition is supplied in an amount sufficientfor at least one application to the oral tissue of the subject at 1 to10 grams per application. For certain of these embodiments, themoisturizer or substantive moisturizing composition is supplied in anamount sufficient for at least 4 applications to the oral tissue of thesubject at 1 to 10 grams per application.

However, for certain embodiments, including any one of theabove embodiments where the moisturizer and antiseptic are applied atthe same time, preferably the moisturizer or substantive moisturizercomposition comprises a solution of the multi-valent cationicantiseptic.

Subjects who are unable to clean their oral tissue, such as ventilatedpatients, are in need of periodic oral tissue cleaning This can becarried out using a de-briding composition, such as a hydrogen peroxidecomposition. Oral debriding refers to removal of plaque and calculusfrom the teeth but also may assist in breaking down thick mucous in theoral cavity that is otherwise difficult to remove. For certainembodiments, including any one of the above method embodiments, themethod further comprises applying a de-briding composition comprisinghydrogen peroxide. For certain embodiments, including any one of theabove oral care kit embodiments, the kit further comprises a de-bridingcomposition, which in one embodiment comprises hydrogen peroxide.

Incertain embodiments, the hydrogen peroxide includes a stabilizingcomponent which maintains the de-briding composition at a pH of 2.5 to4, preferably 2.8 to 3.8, and wherein the de-briding compositionessentially excludes any component which causes a precipitate whencombined with a multi-valent cationic antiseptic used in themulti-valent cationic antiseptic composition when tested according toTest Method F. For certain of these embodiments, the hydrogen peroxideis stabilized with a buffer component selected from the group consistingof buffers such as monovalent alkyl carboxylic acids and alkylphosphoric acids wherein the alkyl group optionally comprises a carbonchain substituted with or interrupted by one or more N, O, or S atoms;polyalkoxylated derivatives such as phosphate or carboxylate terminatedpolyethoxylated and/or propoxylated alkyl alcohols; alpha-hydroxy acidssuch as lactic acid, gluconic acid, citric acid (when used at a pH whereonly one acid group is ionized); amino acids; phosphoric acid; and boricacid. Such buffer components are selected and used at concentrationssuch that a precipitate is not formed when the buffer component iscombined with the multi-valent cationic antiseptic. This can bedetermined according to Test Method F. Preferred acids have onlysubstantially a single acid group at least partially ionized at pH 3.5.For example, phosphoric acid is useful since it has pKa values of 2.15,7.2, and 12.35. Thus, at pH 3.5 there is predominantly a single ionizedgroup. Preferably, the buffer has a pKa less than 3.5, and if itcomprises a second acid functionality the second pKa is greater than 4.5as determined by standard potentiometric titration.

For certain of these embodiments, the de-briding composition is suppliedin an amount sufficient for at least one application to the oral tissueof the subject.

For certain embodiments, including any one of the above method or oralcare kit embodiments which include a moisturizer composition, themoisturizer composition is preferably a substantive moisturizercomposition.

The moisturizer or substantive moisturizer composition as well ascompositions comprising the multi-valent cationic antiseptic describedabove may include at least one additional component selected from thegroup consisting of enhancers, surfactants, hydrophilic compounds,hydrophobic compounds, and combinations thereof.

Enhancer Component:

Compositions included in the present method and kit may include anenhancer to enhance the antimicrobial activity. The activity enhancementmay be especially useful against Gram negative bacteria, such as E. coliand Psuedomonas sp. The enhancer chosen preferably affects the cellenvelope of the bacteria. While not bound by theory, it is presentlybelieved that the enhancer functions by allowing the antiseptic to moreeasily enter the cell cytoplasm and/or by facilitating disruption of thecell envelope. The enhancer component may include a phenolic compound(such as certain antioxidants and parabens), a (C1-C10)monohydroxyalcohol, or a glycol ether (i.e., ether glycol). Various combinations ofenhancers can be used if desired.

In some embodiments, other enhancers may be useful, such as thesiderophores and iron-bonding proteins described in U.S. Ser. No.10/936,949, filed Sep. 8, 2004 entitled “Antimicrobial Compositions andMethods”, if they are formulated such that there is minimal or nointeraction between the multivalent cationic antiseptic and thesiderophore or iron-binding protein; and the sugar and/or alcohols asdescribed in U.S. Ser. No. 60/660,830, filed Mar. 10, 2005 entitled“Methods of Reducing Microbial Contamination.”

One or more enhancers may be used in the compositions included in thepresent method and kit at a suitable level to produce the desiredresult. For certaim embodiments, they are present in a total amountgreater than 0.01 wt-%, preferably in an amount greater than 0.1 wt %,more preferably in an amount greater than 0.2 wt %, even more preferablyin an amount greater than 0.25 wt % and most preferably in an amountgreater than about 0.4 wt % based on the total weight of the ready touse composition. In a preferred embodiment, they are present in a totalamount of no greater than 20 wt-%, based on the total weight of theready to use composition. Such concentrations typically apply tophenolics, ether glycols, and (C5-C10)monohydroxy alcohols. Generally,higher concentrations are needed for (C1-C4)monohydroxy alcohols, asdescribed in greater detail below. The total concentration of theenhancer component relative to the total concentration of the antisepticcomponent is preferably within a range of 10:1 to 1:300 on a weightbasis.

An additional consideration when using an enhancer is the solubility andphysical stability in the compositions. Many of the enhancers discussedherein are insoluble in hydrophobic components such as hydrophobicesters, mineral oil, and petrolatum. It has been found that the additionof a minor amount (typically less than 30 wt-%, preferably less than 20wt-%, and more preferably less than 12 wt-%) of a hydrophilic componentnot only helps dissolve and physically stabilize the composition butimproves the antimicrobial activity as well. Alternatively, the enhancermay be present in excess of the solubility limit provided that thecomposition is physically stable. This may be achieved by utilizing asufficiently viscous composition that stratification (e.g. settling orcreaming) of the antiseptic does not appreciably occur.

A phenolic compound enhancer is typically a compound having thefollowing general structure (including at least one group bonded to thering through an oxygen:

wherein: o is 0 to 3 (especially 1 to 3), m is 1 to 3 (especially 1 to2), each R⁵ independently is alkyl or alkenyl of up to 12 carbon atoms(especially up to 8 carbon atoms) optionally substituted with 0 in or onthe chain (e.g., as a carbonyl group) or OH on the chain, and each R⁶independently is H or alkyl or alkenyl of up to 8 carbon atoms(especially up to 6 carbon atoms) optionally substituted with 0 in or onthe chain (e.g., as a carbonyl group) or OH on the chain, but where R⁶is H, o preferably is 1 or 2.

Examples of phenolic enhancers include, but are not limited to,butylated hydroxy anisole, e.g., 3(2)-tert-butyl-4-methoxyphenol (BHA),2,6-di-tert-butyl-4-methylphenol (BHT),3,5-di-tert-butyl-4-hydroxybenzylphenol, 2,6-di-tert-4-hexylphenol,2,6-di-tert-4-octylphenol, 2,6-di-tert-4-decylphenol,2,6-di-tert-butyl-4-ethylphenol, 2,6-di-tert-4-butylphenol,2,5-di-tert-butylphenol, 3,5-di-tert-butylphenol,4,6-di-tert-butyl-resorcinol, methyl paraben (4-hydroxybenzoic acidmethyl ester), ethyl paraben, propyl paraben, butyl paraben,2-phenoxyethanol, as well as combinations thereof. A preferred group ofthe phenolic derivative compounds is the phenol species having thegeneral structure shown above where R⁶═H and where R⁵ is alkyl oralkenyl of up to 8 carbon atoms, and o is 1, 2, or 3, especially whereat least one R⁵ is butyl and particularly tert-butyl, and especially thenon-toxic members thereof. Some of the preferred phenolic derivativeenhancers are BHA, BHT, methyl paraben, ethyl paraben, propyl paraben,and butyl paraben as well as combinations of these.

One or more phenolic derivative compounds may be used in thecompositions included in the present method and kit at a suitable levelto produce the desired result. The concentrations of the phenoliccompounds in medical-grade compositions may vary widely, but as littleas 0.001 wt-%, based on the total weight of the composition, can beeffective when the above-described esters are present within theabove-noted ranges. In certain embodiments, they are present in a totalamount of at least 0.01 wt-%, more preferably at least 0.10 wt-%, andeven more preferably at least 0.25 wt-%, based on the ready to usecomposition. In a preferred embodiment, they are present in a totalamount of no greater than 8 wt-%, more preferably no greater than 4wt-%, and even more preferably no greater than 2 wt-%, based on theready to use composition. It is preferred that the ratio of the totalphenolic concentration to the total concentration of the antisepticcomponent be within a range of 10:1 to 1:300 on a weight basis.

The above-noted concentrations of the phenolic derivative enhancers arenormally observed unless concentrated formulations for subsequentdilution are intended. On the other hand, the minimum concentration ofthe phenolics and the antiseptic to provide an antimicrobial effect willvary with the particular application.

(C1-C10) Monohydroxy alcohol enhancers include the lower (i.e., C1-C4)monohydroxy alcohols (e.g., methanol, ethanol, isopropanol, and butanol)as well as longer chain (i.e., C5-C10) monohydroxy alcohols (e.g.,isobutanol, t-butanol, octanol, and decanol). In certain preferredembodiments, the alcohols useful in the compositions included in thepresent method and kit are selected from the group consisting ofmethanol, ethanol, isopropyl alcohol, and mixtures thereof.

One or more alcohols may be used in the compositions included in thepresent method and kit at a suitable level to produce the desiredresult.

In a preferred embodiment, the (C1-C4)alcohols arepresent in a total amount of no greater than 50 wt-%, more preferably nogreater than 40 wt-%, and even more preferably no greater than 30 wt-%,based on the total weight of the ready to use composition.

For certain applications, lower alcohols may not be preferred due to thestrong odor and potential for stinging and irritation. This can occurespecially at higher levels. In applications where stinging or burningis a concern, the concentration of (C1-C4)alcohols is preferably lessthan 20%, more preferably less than about 15%.

In certain embodiments, longer chain (i.e., C5-C10) alcohols are presentin a total amount of at least 0.1 wt-%, more preferably at least 0.25wt-%, and even more preferably at least 0.5 wt-%, and most preferably atleast 1.0%, based on the ready to use composition. In a preferredembodiment, the (C5-C 10)alcohols are present in a total amount of nogreater than 10 wt-%, more preferably no greater than 5 wt-%, and evenmore preferably no greater than 2 wt-%, based on the total weight of theready to use composition.

Hydrophilic Component:

Compositions of the present methods and kits can include a hydrophilicor water-soluble component to help solubilize and/or physicallystabilize the antiseptic and/or enhancer component in the compositionand/or to enhance the antimicrobial efficacy and/or the speed ofantimicrobial efficacy. The incorporation of a sufficient amount ofhydrophilic component in hydrophobic ointments for use in applicationssuch as lip care compositions results in compositions with significantlybetter antimicrobial activity both in terms of speed of kill and extentof kill. While not intended to be bound by theory it is believed thatthe incorporation of the hydrophilic component allows more antiseptic tobe available at the surface or to more rapidly diffuse to the surface ofthe ointment during use. Certain compositions may be solutions,emulsions (one liquid/gel/paste dispersed in another liquid/gel/paste),or dispersions (solid in liquid/paste/gel). In general, for improvedantimicrobial activity the ratio of total hydrophilic component to totalhydrophobic component (water insoluble ingredients) should be at least5:95 wt/wt, preferably at least 10:90 wt/wt, more preferably at least15:85 wt/wt and most preferably at least 20:80 wt/wt. Levels as high as30:70, 40:60, 50:50 wt/wt of total hydrophilic component to totalhydrophobic component (water insoluble ingredients) or higher may beappropriate for certain compositions.

Thus, a lower monohydroxy alcohol can function asboth a hydrophilic compound and an enhancer. Preferably, the hydrophiliccomponents include polyhydric alcohols, lower alkyl ethers, and shortchain esters. More preferably, the hydrophilic components includepolyhydric alcohols.

Suitable polyhydric alcohols (i.e., organic compounds having more thanone hydroxyl group) have a molecular weight of less than 500, preferablyless than 400, and more preferably less than 200. Examples of polyhydricalcohols include, but are not limited to, glycerol, propylene glycol,dipropylene glycol, tripropylene glycol, polypropylene glycol,polyethylene glycol, diethylene glycol, pentaerythritol,trimethylolpropane, trimethylolethane, trimethylolbutane, sorbitol,mannitol, xylitol, pantothenol, ethylene glycol adducts of polyhydricalcohol, propylene oxide adducts of polyhydric alcohol, 1,3-butanediol,dipropylene glycol, diglycerine, polyglycerine, erythritol, sorbitan,sugars (e.g., sucrose, glucose, fructose, mannose, xylose, saccharose,trehalose), sugar alcohols, and the like.

Test Method A—Viscosity Test

For selected Examples viscosity was measured at approximately 22° C. atambient pressure using a Brookfield viscometer, model LVT withBrookfield LV spindles. The smallest spindle and the lowest speed arealways chosen for each particular sample such that the viscometer wasoperating in the middle of its range. All samples were allowed toequilibrate at approximately 22° C. for 24 hours prior to measurement.Preferably the viscosity is taken at the lowest speed possible whilestaying within 10-90% and preferably 20-80% of the viscometer range. Inall cases the sample size and container geometry was chosen to ensurethat there were no wall effects. By “wall effects” it is meant theviscosity value is not affected by the container and is essentiallyequivalent to the viscosity taken in an infinitely large container. Forthis reason lower viscosity samples required a larger sample size toaccommodate the larger spindles. The viscosity of each sample was takenas the highest relatively stable reading that was achieved.

Test Method B—Antimicrobial Efficacy Testing

This test method demonstrates the compatibility (or incompatibility) ofPERIDEX antimicrobial mouth rinse with mouth moisturizers by challengingthe mixtures with the bacteria Pseudomonas aeruginosa. If the activityof PERIDEX mixed with a moisturizer is not statistically less than theactivity of PERIDEX alone, then the moisturizer can be said to becompatible with PERIDEX. The ratio of PERIDEX: Moisturizer was chosen tomimic actual product use. When PERIDEX is applied using a swab to aventilated patient approximately 1 to 2 grams is retained in the oralcavity. Many moisturizers are supplied in 2 g unit does packets, fromwhich approximately 1 to 2 grams can be applied. In this assay, theantimicrobial activity of mixtures of PERIDEX and moisturizers is testedby inoculating 1 mL of the mixture with an inoculum of the bacteria. Atthe specified exposure time, a neutralizer for CHG and hydrogen peroxideis added, tubes are vortexed, serially diluted and plated forenumeration of surviving bacteria.

Sample Preparation for Antimicrobial Efficacy Test

Test mixtures were prepared at 2 levels (4.8 g or 6.4 g) of each of theabove moisturizers with 9 g of PERIDEX solution. PERIDEX is a solutionof 0.12% chlorhexidine gluconate (1,11-hexamethylene bis[5-(p-chlorophenyl)biguanide]di-D-gluconate) in a base containing water,11.6% alcohol, glycerin, PEG-40 sorbitan diisostearate, flavor, sodiumsaccharin, and FD&C Blue No. 1 commercially available from 3M ESPEDental Products of St. Paul, Minn. The resulting mixtures were vortexedto mix vigorously for a period of 2 minutes. The mixtures were allowedto incubate for 15 minutes prior to centrifugation at 5000 rpm for 30min. The samples were centrifuged in order to settle insoluble material.After centrifugation, supernatant was carefully transferred to a newvial and submitted for Antimicrobial Efficacy Testing, see Table 5 andHPLC recovery of CHG testing, see Table 7.

Test Organism for Antimicrobial Efficacy Test

The test organism for this assay was Pseudomonas aeruginosa (ATCC27853). The initial suspension was prepared by suspending bacterialcolonies from an overnight growth plate on Tryptic Soy Agar inphosphate-buffered water (PBW). The PBW was prepared as follows: To 500ml deionized water was added 0.34 g potassium dihydrogen phosphate. ThepH was adjusted to 7.2 using 10N sodium hydroxide. The contents werediluted to 1 liter using deionized water. This was filter sterilized. A0.5 McFarland turbidity standard was used to obtain a cell density ofapproximately 1.5×10⁸ CFU/mL.

Test Materials for Antimicrobial Efficacy Test

Each moisturizer was mixed with PERIDEX in defined ratios as describedabove. PERIDEX and moisturizer were weighed into glass vials, and mixedby vortexing for a period of 2 minutes. Moisturizer samples containingCHG were not mixed with PERIDEX. Testing was conducted with 1 mL of themixtures. Duplicate 1 mL samples were transferred into 50 mL conicaltubes with a positive displacement pipet. The controls for the testingwere 1 mL of PBW (for direct enumeration of inoculum) and 1 mL PERIDEX.

Inoculum Preparation for Antimicrobial Efficacy Test

The inoculum was prepared by diluting the initial suspension 10 fold inPBW. The inoculum suspension was enumerated at the beginning and end ofthe test period. The final count was within 0.1 log/mL of the initialcount. Each 1 mL test sample was inoculated with approximately 5.8 logsbacteria.

Neutralizing Broth: The D/E broth is Dey Engley neutralizing brothpurchased as a solid and reconstituted according to directions fromDifco Laboratories, Detroit Michigan. The D/E broth was supplementedwith filter-sterilized Catalase (from bovine liver, Calbiochem, 0.2g/liter broth) immediately before use.

Test Method B—Measurement of Antimicrobial Activity:

Forty microliters of the bacterial inoculum was added to one mL of thetest mixtures, vortexed and let sit at ambient temperature. Timingstarted as soon as the bacteria were added. After 2.5 minutes, 20 mL ofD/E broth containing catalase was added and vortexed vigorously.

Dilutions were prepared in PBW, and 1 mL, in duplicate, pipetted intoAerobic

Count Petrifilm Plates, 3M Company. All plates were incubated at 35° C.for 43 hours. Plates were counted with the 3M Petrifilm Plate Reader,and confirmed manually. Colony Forming Units (CFU) were counted,duplicate plates averaged and multiplied by the dilution factor forCFU/mL, and multiplied by the total test volume after neutralization (21mL) for the CFU/test sample. Log10 CFU/test of duplicate tests wereaveraged and the log10 reduction was calculated from the PBW controls.

The mixtures of PERIDEX with the comparative examples C1, C2, C3 andexperimental examples Ex 1, Ex 2 and Ex 3 were tested according to theabove Antimicrobial Efficacy Test. The results are shown in Table 5,below. Mixtures of PERIDEX with KIMVENT Mouth Moisturizer, 3M XanthanGel and 3M Guar Gel did not significantly impact the antimicrobialefficacy of CHG. All performed equivalent to PERIDEX oral rinse testedunder the same conditions. 3M Guar Gel with 0.12% CHG also performedsimilarly to the PERIDEX control. In contrast, mixtures of PERIDEX withORALBALANCE Gel and TOOTHETTE Mouth moisturizer significantly decreasedthe antimicrobial efficacy of CHG. Both ORALBALANCE Gel and TOOTHETTEmoisturizers achieved less than 2 log reduction of bacteria.

The TOOTHETTE mouth moisturizer C3 was tested in increasing ratios ofmoisturizer:PERIDEX according to the Antimicrobial Efficacy Test,described above. The results are shown in Table 6, below. Virtuallycomplete kill of bacteria is achieved with PERIDEX when it isuninhibited by moisturizer C3. However, as little as 0.2 grams ofTOOTHETTE moisturizer impacts the antimicrobial efficacy of PERIDEX.With increasing levels of moisturizer C3, the log reduction is furtherreduced.

Additional test mixtures were prepared across a range of levels (1.2 g ,2.4 g, 4.8 g, 6.0 g, and 6.4 g) of commercially available C3 moisturizer(TOOTHETTE Mouth Moisturizer), each weighed into a vial containing 9 gof PERIDEX solution. The resulting mixtures were vortexed for a periodof 2 minutes. The mixtures were allowed to incubate for 15 minutes priorto centrifugation at 5000 rpm for 30 min. After centrifugation,supernatant was carefully transferred to a new vial and submitted forAntimicrobial Efficacy Testing, see Table 6 and HPLC recovery of CHGtesting, see Table 8.

Test Method C—Precent Recovery of CHG by HPLC Analysis

HPLC analysis was performed to approximate the amount of available CHG,not “inhibited” by the moisturizer. Reverse phase gradient HPLC analysisof the provided solutions/suspensions were performed using an Agilent1200 SLMSD system consisting of a binary SL pump, well plateautosampler, heated column compartment and diode array absorbancedetector (DAD). Separations were performed under the followingchromatographic conditions. The sample injection volume was 10 μL. TheHPLC column used was a 4.6×75 mm, Zorbax 3.5 μm SB-C18 column (Agilent).Column temperature was maintained at 35° C. The flow rate was 0.5mL/min. The mobile phase consisted of 2 solvent mixtures: solvent A=100%water+0.1% v/v TFA and Solvent B=100% Methanol+0.1% v/v TFA. Aprogrammed linear gradient mobile phase was used: 90/10 Solvent A/Solvent B (0 minute hold) to 100% B (5 minute hold) over eight minutes(linear). Step back to initial conditions, 5 minute re-equilibration.Elution time for chlorhexidine was approximately 13.1 minutes. Detectionwas by UV-VIS at 258 nm (reference=450 nm). A linear regressioncalibration curve of the equivalent chlorhexidine response was performedusing volumetric standard solutions at 4 levels of chlorhexidine freebase. The standards were run both before and after the sampleinjections. Absorbance data was averaged from duplicate injections fromeach sample, as well as duplicate samples and concentrations determinedbased on standards. The equivalent concentrations of CHG were calculatedbased on the 1.78 fold difference in molecular weights. The CHGcontrol-PERIDEX control is calculated to be 0.133 wt % from HPLC.

Prior to analysis by HPLC samples were prepared in the following manner.Quantitatively, 50-150 mg of each of the above test mixtures weretransferred to a vial. An amount of 5 mL of extraction solvent (90/10water/methanol+0.1% v/v TFA) was added to the test mixtures. All sampleswere vortexed briefly and allowed to extract/dissolve for a period of 4hours at room temperature on an orbital shaker. After extraction for 4hours, samples were transferred to HPLC vials.

Test Method D—Moisturizer Film Formation and Caking

An amount of 0.2 grams of a moisturizer was weighed onto the center of a2.5×2.5 cm (1×1 inch) square marked on a clear plastic petri dish, 15 mmpolystyrene plastic disposable sterile dish (Cat #25384-088, VWR WestChester, Pa.). The 0.2 grams of moisturizer was spread evenly tocompletely coat the 2.5×2.5 cm (1×1 inch) area of a clear plastic petridish. Films were left to dry at room temperature in open air conditionsfor 2 hours. After 2 hours, visual and physical observations were madefor each dried film. The fraction of area still covered by the driedfilm was visually observed. Films were physically characterized bypeeling the film off of the plastic dish and observing the amount peeledoff of the petri dish as a single piece, and the ease with which thefilm can be torn or broken when pulled. Results are shown in Table 10,below.

Test Method E—Demonstration of Substativity

-   General Description of Substantivity Test Method:

A substantive moisturizer composition was defined by the ease with whichdyed moisturizer sample was washed away from an artificial skin surface,VITRO-SKIN available from IMS Inc. of Portland, Md.). Moisturizersamples included competitive sample C4, Example Ex4, dilutions of Ex4 indistilled water (represented as wt % Ex4), and distilled water alone asa control.

-   Viscosity Measurement of Moisturizer Samples:

The viscosity of each moisturizer sample or diluted moisturizer samplewas measured using a Brookfield viscometer; model LVT with Brookfield LVspindles, as described in the viscosity test. The viscosity of eachsample is shown with the results in Table 11.

-   Dying of Moisturizer Samples for Substantivity Testing:

After measurement of viscosity, each sample was dyed to make themoisturizer sample easily visible in water. The dye was selected toensure that it does not stain VITRO-SKIN. For the current example,moisturizers were dyed by adding 0.3 grams of BETADINE (10% PovidoneIodine, available from Purdue Products L.P. of Stamford, Conn.) to 5grams of moisturizer or diluted moisturizer sample. The staining ofVITRO-SKIN was verified by placing a drop of BETADINE on the topographyside of VITRO-SKIN (prepared as described below), waiting for 1 minute,washing it off in distilled water, and visually confirming the absenceof color. For moisturizer samples that are incompatible with povidoneiodine, another dye could be used that, similarly, does not stainVITRO-SKIN.

-   Preparation of VITRO-SKIN for Substantivity Testing:

VITRO-SKIN was pre-hydrated in a chamber at 75° F. (24° C.) and 45%relative humidity (RH). The pre-hydrated VITRO-SKIN was cut into 2.5×2.5cm (1×1 inch) squares and a black permanent ink marker was used to markthe edges of VITRO-SKIN to make it more visible for manipulation. Thesquares of VITRO-SKIN were dunked in distilled water for 5 seconds tosimulate a moist tissue surface, and placed at the bottom of a dry 8 oz.glass jar, with the topography (non-shiny) side facing up.

-   Substantivity Test Method:

Each dyed sample (0.5 grams) was pipetted onto the surface of theprepared VITRO-SKIN square in the bottom of its 8 oz. glass jar.Observations were made regarding the surface interaction between thesample and the VITRO-SKIN. Distilled water (25 mL) was added to the jarby pipetting the water down the side of the jar, carefully, to ensurethat the contact between the sample and the VITRO-SKIN was not disturbedby the flow of water. After 1 minute (starting at the time water beginsto enter the jar), the VITRO-SKIN and any contacting, dyed sample wascarefully removed from the jar using tweezers, placed on a clean, drypaper towel, and photographed. The sample was carefully returned to thejar and re-submerged in the water, where it was allowed sit forapproximately 1 hour and 30 minutes. After 1 hour and 30 minutes, theVITRO-SKIN and any contacting, dyed sample was, again, carefully removedfrom the jar using tweezers, placed on a clean, dry paper towel, andphotographed. The photographed images were visually characterizedaccording to the amount of surface area covered by the dyed sample, theintensity of the dyed sample, and the relative thickness of the film orpool of dyed sample remaining on the VITRO-SKIN. The results forsubstantivity of the tested moisturizers are summarized in Table 11 withreported observations made initially, after 1 minute and after 1.5hours.

Test Method—Evaluation Precipitate Formation

It is thought that some excipients (inactives) may form a CHG complex,which is visible as a precipitate. Thus, CHG which complexes with anexcipient, forming a precipitate would not be available forantimicrobial efficacy. The purpose of the precipitation formationtesting was to observe the potential of an excipient to form aprecipitates with CHG under the following test conditions.

A solution containing 3.72% (w/w) CHG was prepared by diluting 18.6% w/wCHG stock solution with water. Sample excipient solutions were preparedwith distilled water to various concentrations of excipients accordingto Tables 12-16, below. The pH of the solutions was then adjusted toboth a low pH and a high pH using either gluconic acid or NaOH. Then 6mL of each pH adjusted excipient sample solution was transferred into aseparate vial and an equal amount (6 mL) of 3.72% CHG was added to forma 1:1 mixture (12 mL total). After combining the CHG solution with theexcipient solution, the vial of the mixture was briefly swirled to mix.The mixtures were visually assessed for the presence/formation of aprecipitate within 30 minutes. The results are shown in Tables P1-P5,where “Y” means precipitate was observed; “N” means no precipitate wasobserved; “*1” means the mixture could not be tested because a gel-likemass was formed when adding gluconic acid to reduce the pH down; and“*2” means the mixture could not be tested because it started to thickenwhen adding NaOH to raise the pH. For all the samples evaluated forformation of precipitate the weight percent of CHG was 3.72%, thisequated to 0.22 grams CHG. Since CHG has a molecular weight of 897.8;each sample had 0.245 mMol CHG, which is 0.123 milliequivalents of CHG.

For Test Method B2 the above Test Method B was followed, with thefollowing changes:

-   -   1. Bacteria was MRSA (methicillin-resistant Staphylococcus        aureus), ATCC 33592, instead of P. auruginosa.    -   2. Inoculum level was approximately 6.2 logs, instead of 5.8        logs.    -   3. Incubation time with MRSA was 4 minutes, instead of 2.5        minutes.    -   4. Neutralizer was Neutralizing Buffer, instead of D/E        Neutralizing Broth.    -   5. Incubation of the Petrifilm plates was 38 hours, instead of        43 hours.

HPLC Test Method C2—Second % Recovery of CHG by HPLC Analysis

HPLC analysis was performed to approximate the amount of available CHG,not “inhibited” by the moisturizer. Reverse phase gradient HPLC analysisof the provided solutions/suspensions were performed using an Agilent1100 system consisting of a binary pump, 100-position autosampler,heated column compartment and diode array absorbance detector (DAD).Separations were performed under the following chromatographicconditions. The sample injection volume was 0.5 uL. The HPLC column usedwas an Agilent Zorbax 4.6×75 mm, 3.5 μm SB-C18 column. The columntemperature was maintained at 40° C. The flow rate was 0.5 mL/min. Themobile phase consisted of 2 solvent mixtures: solvent A=100% water+0.1%v/v TFA and Solvent B=100% Methanol+0.1% v/v TFA. A programmed lineargradient mobile phase was used: 70/30 Solvent A/Solvent B (2 minutehold) to 100% B (2 minute hold) over 15 minutes (linear). Step back toinitial conditions, 5 minute re-equilibration. Elution time forchlorhexidine was approximately 12.7 minutes. Detection was by UV-VIS at260 nm (reference=550 nm). A percent recovery value was calculated foreach inhibitory agent (IA) by ratioing the integrated peak area for theIA with the integrated peak area for the control sample *100 (i.e.[(Integrated peak area IA/Integrated peak area control)*100]). Thepercent recovery of CHG results are reported in table 18, below.

Test Method B3—Antimicrobial Efficacy Testing Test Organism forAntimicrobial Efficacy Test Method B3

The test organism for this assay was Pseudomonas aeruginosa (ATCC27853). The initial suspension was prepared by suspending bacterialcolonies from overnight growth on Sheep Blood Agar in 0.3 mMphosphate-buffered water (PBW). The stock PBW (0.25M) was prepared asfollows: To 500 ml deionized water was added 34 g potassium dihydrogenphosphate. The pH was adjusted to 7.2 using 10N sodium hydroxide. Thecontents were diluted to 1 liter using deionized water. This was filtersterilized. Then 0.62 microLiters of stock solution were added to 500 mLDI water making a 0.3 mM PBW solution. A 0.5 McFarland turbiditystandard was used to obtain a cell density of approximately 1.5×10⁸CFU/mL. The suspension was enumerated at the beginning of the testperiod.

Inoculum Preparation for Antimicrobial Efficacy Test B3

The inoculum was prepared by diluting the initial suspension 10-fold inPBW. Each test sample was inoculated with approximately 5.5 logsbacteria.

Neutralizing Broth: D/E Neutralizing Broth was purchased as a solid andreconstituted according to directions from Difco Laboratories, DetroitMichigan.

Test Materials for Antimicrobial Efficacy Test B3

The test mixture was prepared at a ratio of 1 mL PERIDEX plus 1 gmoisturizer Example 4, plus 0.5 mL phosphate buffered water (PBW) andmixed by vortexing. The mixture was incubated at ambient temperature for5 minutes prior to inoculation. The controls for the testing were 1 mLof PBW (for direct enumeration of inoculum) and 1 mL PERIDEX.

Test Method B3—Measurement of Antimicrobial Activity:

The mixture and controls were inoculated with forty microliters ofbacterial inoculum per mL, and vortexed for 20 seconds. After 5 minutesat ambient temperature, 1 mL of the inoculated test mixture or controlswere added to 20 mL D/E Neutralizing Broth and vortexed.

Dilutions were prepared in PBW, and 1 mL, in duplicate, was pipettedinto Aerobic Count Petrifilm Plates, 3M Company. All plates wereincubated at 37° C. for 48 hours.

Plates were counted with the 3M Petrifilm Plate Reader, and confirmedmanually. Colony Forming Units (CFU) were recorded, duplicate platesaveraged and multiplied by the dilution factor for CFU/mL, andmultiplied by the total test volume after neutralization (21 mL) for theCFU/test sample. Log10 CFU/test of multiple tests were averaged and thelog10 reduction was calculated from the mean PBW control. The log10reduction of Pseudomonas for the test mixture of 1:1:0.5 (Peridex:3Mmoisturizer:PBW) was 4.4 log units. The log10 reduction of Pseudomonasfor the Control mixture of 1:1:0.5 (Peridex:PBW:PBW) was 4.5 log units.
